If it takes 10 people 6 days to do a home improvement, how long would 4 take

60 person days/job

(1/60) job/person day

(1/60)job/person day *(4) persons = 4/60 job/day = 1/15 job/day
so
15 days

4/10 as many people means 10/4 as long to work.

5/2 * 6 = 15

To find out how long it would take 4 people to do the home improvement, we can use the concept of man-days.

First, we need to calculate the total number of man-days required to complete the home improvement project. We can do this by multiplying the number of people by the number of days taken by those people. In this case, it would be 10 people * 6 days = 60 man-days.

Next, we can determine how many days it would take for 4 people to complete the same amount of work. To do this, divide the total number of man-days (60) by the number of people (4). So, 60 man-days / 4 people = 15 days.

Therefore, it would take 4 people approximately 15 days to complete the home improvement project.
